Engrams emerging as the basic unit of memory

Though scientist Richard Semon introduced the concept of the "engram" 115 years ago to posit a neural basis for memory, direct evidence for engrams has only begun to accumulate recently as sophisticated technologies and methods ...

Memory like a sieve – or not

Humans are not only capable of forming memories but also recalling these memories years later. However, with advancing age many of us face difficulties with forming new memories, a process usually referred to as age-induced ...
